CVE-2026-32975Network attack vector

Authorization bypass via mutable Zalouser group names

Published Mar 29, 2026 · Updated Mar 29, 2026

Weak authorization in OpenClaw before 2026.3.12 allows remote attackers to route unintended Zalouser group messages to the agent. The Zalouser allowlist compares attacker-controlled display names and normalized slugs against channels.zalouser.groups instead of requiring stable group IDs. Exploitation requires name-based group entries and a permissive sender allowlist; a duplicate-name group can then reach the agent.
